Coating Cracking

The essence of coating cracking is that the internal stress exceeds the fracture toughness of the coating. The core of the solution is "stress reduction + toughening": control the coating thickness to avoid stress accumulation from excessive thickness, adopt mild curing conditions to allow stress...

Pinholes / missed coating

The essence of pinholes and missed coating is that the coating liquid fails to form a continuous and complete covering film. The solution approach is "defoam + thicken + clean surface": defoam the coating liquid to eliminate bubble sources, appropriately increase coating amount to ensure the liqu...
